Low quality, never! They're all so incredibly cute and expressive! I love the parents here (they're seriously darling), Rarity looks lovely as always and the lighting throughout the piece is just beautiful... it's a very warm and cozy little scene. Great work!

true enough. but it is my headcannon that Rari-dad is in fact, an Earth pony. This makes Sweetie's low magic usage make sense, and for why Rarity stays in Ponyville rather than move to Canterlot. yay headcannon

I think Sweetie Belle's just young, though of course, there's nothing wrong with headcanon... I have some of my own that I like to prescribe to as well. But as far as artistic renditions, since we have no evidence either way I think people should feel free to interpret him as they choose.
